Ever heard of sage Agastya? He is one of the seven rishis (Saptarishi) mentioned in the Vedas. Commonly known as Vegetable Humming Bird in English, the Agastya (Sanskrit name) plant derives its name from rishi Agastya. One of the theories states that rishi Agastya, also considered as the father of the Siddha system of medicine held a deep love for the plant, which is the reason why the plant is named so. Dear to the munis, the flowers of Agastya bloom in Sharad Ritu (autumn season) on the day when the Agastya star can be seen. The flowers are also offered to Lord Shiva to please him.

Holding the botanical name Sesbania grandiflora, the plant is known by various other names like Agasti in Hindi. The flower of Agasti is called ‘August flower’ and is found in white, red and yellow colours. Each part of the Agastya plant serves some medicinal purpose or the other, as mentioned in Ayurveda.
